摘要

为了提高DC04钢板耐冲击度时的测量精度

提出了一种局部降噪方法以降低钢板在高速冲击过程中的局部强光.此方法主要运用线性变换进行计算

使用高斯低通滤波等仪器进行测量比较

运用图像评价的标准进行选择.这种方法运用图片中提取的灰度信息来确定被干扰的区域

灰度阶跃值的变化可以确定光强弱的变化

可以确定受干扰的区域的大小以及方向等信息;运用PSNR评价标准来确定灰度图片的截止频率;把灰度图像通过线性的变换调至正常的范围内

代替强光区域进行之后的运算.最终经过实验检验比较得到了较高的精度.

Abstract

In order to improve the measurement accuracy of impact resistance of DC04 steel plate

a local noise reduction method was proposed to reduce the local intensity of light during high-speed impact of steel plate.Methods Linear transformation was used for calculation

Gauss low-pass filter and other instruments were used for measurement and comparison

and image evaluation criteria were used for selection. In this method

the gray information extracted from the image is used to determine the disturbed area

the change of gray step value can determine the change of light intensity

the size and direction of the disturbed area

etc. The cut-off frequency of the gray image is determined by PSNR evaluation criterion

and the gray image is adjusted to the normal range by linear transformation instead of the strong light area

then carries out the operation. Finally

a high accuracy has been obtained through experimental verification.
